Enumeration Type Documentation

enum DDS_ReliabilityQosPolicyKind

Kinds of reliability.

QoS:

DDS_ReliabilityQosPolicy

Enumerator:

DDS_BEST_EFFORT_RELIABILITY_QOS

Indicates that it is acceptable to not retry propagation of any samples. Presumably new values for the samples are generated often enough that it is not necessary to re-send or acknowledge any samples. [default] for DDSDataReader and DDSTopic

DDS_RELIABLE_RELIABILITY_QOS

Specifies RTI Data Distribution Service will attempt to deliver all samples in its history. Missed samples may be retried. In steady-state (no modifications communicated via the DDSDataWriter) RTI Data Distribution Service guarantees that all samples in the DDSDataWriter history will eventually be delivered to all the DDSDataReader objects (subject to timeouts that indicate loss of communication with a particular DDSSubscriber). Outside steady state the HISTORY and RESOURCE_LIMITS policies will determine how samples become part of the history and whether samples can be discarded from it. [default] for DDSDataWriter
